I have a standard bore 1948 235 . Cast iron pistons .

Can I use standard 1955 > 235 alloy pistons (is the gudgeon height the same) ?

Yes, the wrist pin height and diameter is the same for both pistons. A 216 can be bored out .0625" and use 235 pistons, also. It becomes a 224 cubic inch when that is done.

The lighter weight pistons put a lot less stress on the Babbit bearings, and the engine accelerates quicker since those heavy iron pistons don't have to change directions several times a second. At 2000 RPM, they're starting and stopping 33 times a second!

That was my thinking Jerry , although this engine is new , I think swapping the original cast iron pistons for alloy has to be of benefit to the engine life , not that I'm ever going to wear it out (it's taken me over 23 yrs to do just 80,000 miles in this truck . I'm only doing the engine change due to massive cracked block in the original 216 .
